Is there ever an issue in Zoom where you get feedback if multiple people have their mics on at once? I have that happen in other platforms.

Another useful host button to find: disable people's videos. Sometimes people leave the video on accidentally when something is happening in the background (someone exiting a shower is what happens more often than we think)

Everything that you say in the chat to Everyone will be saved and reblogged

Brandy (Ellensburg, WA)

Under Reactions: You can clap and thumbs up.

If you click on Participants then it will show you a list of “Raise Hand” “Yes” “No” “Go Slower” “Go Faster” “More”

Brandy (Ellensburg, WA)

You have a list of all the people on the call. If you cursor over Sue then you have a menu of options in the … You can “Chat” or “Pin Video”

any multiple of 3-4-5 (i.e 2 * 3-4-5)

multiples

Brandy (Ellensburg, WA)

48:01

So, what do you notice?

Cezar (Vienna, VA)

48:21

I notice something about odd^2 + odd^2...

Cezar (Vienna, VA)

49:58

if all three numbers are even, then we can divide by 2 (so it is not a primitive triplet)

Tatiana Ter-Saakov

50:44

square of any odd number can be a difference of perfect squares

Cezar (Vienna, VA)

53:32

(even)^2 has to be a multiple of ….

Cezar (Vienna, VA)

53:49

we can write it as an even number + 1

Tatiana Ter-Saakov

01:11:24

one thing to be aware of : once we are in breakout room we don’t see your whiteboard any more

Rodi Steinig (Philadelphia)

01:11:25

I can't get the chat and participants window back on the right like before.

Brandy (Ellensburg, WA)

01:11:41

You’ll need to click on them again from the bottom

Rodi Steinig (Philadelphia)

When I do that I get it in the middle of the screen on top of the video

Rodi Steinig (Philadelphia)

01:12:25

I can drag it to the right

spotlight

Cezar (Vienna, VA)

01:14:33

I think it is missing a 4 in front of the parantheses

Cezar (Vienna, VA)

01:14:52

it should be 4(m^2 + n^2 - m - n) + 2

Susan (Richmond, CA)

01:15:22

t should be 4(m^2 + n^2 - m - n) + 2

Susan (Richmond, CA)

01:15:58

t should be 2(m^2 + n^2 - m - n+1}

Cezar (Vienna, VA)

01:16:18

Looks good to me

Susan (Richmond, CA)

01:17:04

2(m^2 + n^2 - 2m -2 n+1}

Will this session be recorded and available later?

Rodi Steinig (Philadelphia)

Yes, Sue will post it on her blog

Brandy (Ellensburg, WA)

01:30:31

Might want to re-mute everyone

Tatiana Ter-Saakov

01:32:21

should we consider reminders mod 4

Maria D (NC) Natural Math

01:32:41

mod is a good bridge from here!

My apologies, I need to leave. It as nice to see you all!

leg + 1 = hypotenuse

Cezar (Vienna, VA)

01:35:50

or leg + (leg + 1)

01:40:02

I have to go. See you later, math friends! Thank you for the joyful math circle!

I had to exit the meeting for a couple of minutes and then come back in. I wanted to see any chat that I missed but I only see chat entries from when I re-entered. Nothing from before is available. Is there a way to access that?

Rodi Steinig (Philadelphia)

01:43:59

Is there a way to open up a Zoom classroom and practice individually before running a class?

Lhianna B (Philadelphia)

01:46:19

SORRY, i have to leave. really great to see you, Sue! thank you for sharing this experience

Andres (Colombia)

01:46:26

Bye!

Cezar (Vienna, VA)

01:46:29

so we can generate triples by starting with an odd number leg, then squaring it, subtracting 1, and dividing by 2 which will give us the second leg

Rodi Steinig (Philadelphia)

01:47:28

I need to get going too. Thank you Sue! This has been so helpful!

Rodi Steinig (Philadelphia)

01:47:44

Bye everyone! I hope you all have good Math Circles online!

Andres (Colombia)

01:47:48

Thanks Sue, this was really helpful! Need 2 go now. Bye!

Brandy (Ellensburg, WA)

I have an idea about finding a triplet starting with 15
